Please help.
I am developing a commercial program using OpenGL, and I am using feedback buffer for cad plotting .
Since sometime, on the Radeon graphic board, calling glRenderMode(GL_FEEDBACK) does not return the correct result.
On the other hand, there is no problem with the NVIDIA graphics board.
Currently, I recommend only the NVIDIA graphics board for my program.
I wonder whether it is real that glRenderMode(GL_FEEDBACK) does not work properly on the Radeon graphic board, or whether it works normally by change the driver setting properly.
If there are any solutions, please let me know.
